Eye-watering performance at an eye-watering price.

BMW Australia locks in M4 GTS

Australia's most committed BMW enthusiasts will soon have an opportunity to take home the brand's most focused model.

BMW's local arm has locked in 25 examples of the high-performance M4 GTS coupe which will arrive in September.

The ultimate M4 will be the one of the most expensive models in the range, priced from $295,000 plus on-road costs – roughly double the $149,900 ticket for the regular M4 coupe.

Supporters of the brand could get hold of an X5M super-SUV for the Monday to Friday commute, a manual M2 Coupe for weekends and a retro BMW R nineT motorcycle for roughly the same price as the M4 GTS.

But they would miss out on the high-tech kit that makes BMW's high-performance flagship special. The twin-turbocharged six-cylinder engine under the GTS' carbon fibre bonnet uses world-first water injection technology to control intake temperatures, allowing it to produce a massive 368kW of power and 600Nm of torque.

Oversized ceramic brakes and lightweight materials help the coupe weigh 30kg less than a regular model, allowing it to reach 100km/h in 3.8 seconds. Cornering is accounted for by tuneable carbon-fibre spoilers and fully adjustable coil-over suspension and sticky Michelin Pilot Sport Cup 2 tyres that cloak 19-inch wheels on the front and 20-inch rims on the back.

BMW says the machine has a top speed of 305km/h, and that it can lap the Nurburgring Nordschleife circuit in 7 minutes and 28 seconds – on par with Porsche claimed for its V10-powered, carbon-fibre chassis Carrera GT supercar.

The M4 GTS follows in the footsteps of 2003's M3 CSL, the ultimate BMW performance car of its era that added $68,000 to the then-regular M3's $142,000 asking price. While that car was considered expensive at the time, its superior performance, iconic looks and relative rarity (just over two dozen landed in Australia) ensures that the M3 CSL is worth considerably more than regular models today.
